8 – How do I change the main channel url?

I’ve created a Feed display using a view in Drupal 8. Up at the top of the feed results I see this:

  <channel>
    <title>My Title</title>
    <link>https://www.mydomain.com/</link>
    <description></description>
    <language>en</language>

How do I change the <link> value?
